RFL4120

Flagship class-AB 800W RMS @4Ω 4-channel Hi-Fi amplifier with complete variable active x-over

Introduction

The MTX RFL4120 (4x120W RMS) four-channel amplifier is a model of sound quality. It is at the cutting edge of technology and performance. This is the standard of the brand's amplifiers for sound quality. All its construction and the components used exude sound quality. We use Sanken brand transistors on the power stages. These are hi-fi transistors. We take incredible care in aligning them to keep the distortion as low as possible. The flexibility and flexibility of its filter allow it to filter all options (front rear, subwoofer, bass, medium or treble, anything is possible).

Features

Exceptional sound quality in class-AB.
High quality components (Sanken hi-fi grade transistors).
All aluminum construction with backlit window to admire the components.
Modularity 4, 3 or 2 channels.
Flexibility of the active filter capable of doing everything (high pass, low pass, variable band pass from 40 to 5000Hz).
EBC control on channels 3 and 4.
2x50mm² terminal block
